Hi Roger, It looks like your version of CC 2015 [1014445] is not current. The latest Lightroom CC version is CC 2015.12 [ 1126820 ]. Try update to the current version of Lightroom using the Adobe Creative Cloud app (see https://helpx.adobe.com/lightroom/kb/keeping-lightroom-up-to-date.html). Or you can try to download and install manually from here:

Thank you for the help, I had to go all the way to Solution 5: Remove the affected Creative Cloud application, and then reinstall it. It seems to be working and I hope it will work for a long time now.Time to go to sleep (Paris, Stockholm time)Best RegardsRoger
